Measurement-induced phase transitions in sparse nonlocal scramblers

  title={Measurement-induced phase transitions in sparse nonlocal scramblers},
  author={Tomohiro Hashizume and Gregory S. Bentsen and Andrew J. Daley},
Measurement-induced phase transitions arise due to a competition between the scrambling of quantum information in a many-body system and local measurements. In this work we investigate these transitions in different classes of fast scramblers, systems that scramble quantum information as quickly as is conjectured to be possible – on a timescale proportional to the logarithm of the system size. In particular, we consider sets of deterministic sparse couplings that naturally interpolate between… Expand

Fast scrambling on sparse graphs
It is proposed that a logarithmic scrambling time can be achieved in most quantum systems with sparse connectivity, and how quantum chaos is not universally related to scrambling is elucidated. Expand
Dynamical Purification Phase Transition Induced by Quantum Measurements
Continuously monitoring the environment of a quantum many-body system reduces the entropy of (purifies) the reduced density matrix of the system, conditional on the outcomes of the measurements. WeExpand

The competition between scrambling unitary evolution and projective measurements leads to a phase transition in the dynamics of quantum entanglement. Here, we demonstrate that the nature of thisExpand
Quantum Zeno effect and the many-body entanglement transition
We introduce and explore a one-dimensional ``hybrid'' quantum circuit model consisting of both unitary gates and projective measurements. While the unitary gates are drawn from a random distributionExpand

A bstractMany proposed quantum mechanical models of black holes include highly non-local interactions. The time required for thermalization to occur in such models should reflect the relaxation timesExpand
Treelike Interactions and Fast Scrambling with Cold Atoms.
An experimentally realizable quantum spin model that exhibits fast scrambling, based on nonlocal interactions that couple sites whose separation is a power of 2.5, offers a test case for experimentally observing the emergent geometry of a quantum many-body system. Expand
